The Plymouth GTX arrived in 1967 as Mopar’s no-compromise muscle car — a factory hot rod that skipped the option sheets and came standard with performance. Built on the B-body platform shared with the Belvedere, the GTX was Plymouth’s answer to the Pontiac GTO: a serious, big-block machine aimed at buyers who wanted maximum performance without compromise. By 1970, the GTX had reached its aesthetic and mechanical peak, wearing some of the boldest High Impact paint colors ever offered by an American manufacturer and carrying engine options that placed it firmly among the most powerful production cars of the era. Today, authentic big-block GTX examples are among the most coveted B-body Mopars in the collector market, and ground-up restored examples command consistent premiums for their combination of rarity, visual drama, and mechanical integrity.

This 1970 example has undergone a detailed, nut-and-bolt restoration that respects the car’s factory heritage while bringing it into the modern era with thoughtfully chosen upgrades. The exterior wears its correct Limelight High Impact Paint — one of the most striking color options Plymouth offered that year — paired with the correct Performance Hood Treatment, creating a presence that is both period-authentic and visually arresting. Ridler 651 wheels in staggered 18 and 20-inch fitment complete a stance that is aggressive without overstepping the car’s original character.

Under the hood sits the correct 440 cubic inch Chrysler V8, brought up to date with a Holley Sniper electronic fuel injection system on what is otherwise a correct and numbers-appropriate engine package. The result is a combination that delivers the authentic big-block character GTX buyers demanded in 1970, paired with modern cold-start reliability and fuel efficiency. Power is routed through the correct A727 TorqueFlite 3-speed automatic transmission — one of the most robust automatic gearboxes of the muscle car era — to an 8.75-inch rear axle with 3.23 gears, a well-balanced ratio that suits both street driving and spirited acceleration. Power front disc and rear drum brakes, power steering, and lowering blocks round out a drivetrain that has been comprehensively sorted for real-world usability.

Inside, the cabin presents in correct Black and Charcoal vinyl bucket seats with a matching correct center console, preserving the GTX’s factory-correct character throughout. Dakota Digital VHX instrumentation provides modern telemetry within a period-sympathetic presentation, while a Vintage Air modern air conditioning system ensures year-round comfort without compromising the interior’s visual integrity. The car is accompanied by its original Broadcast Sheet, service receipts, and receipts for upgrades — a documentation package that supports both the restoration’s authenticity and its long-term collectibility.
